To all whom, it may concern:

Be it known that I, LEVI C. HAY, of Washington, in the District of Columbia, have invented a new and useful Improvement in Method of Producing Forms for Rule-and- Figure Tables, of which the following is a specification.

My invention has reference to the production of linotype-forms for printing rule-andfigure work, the aim being to produce perfect vertical rules upon and integral with the slugs or linotypes in order to avoid the use of brass rules and the labor and expense incident to their insertion.

Heretofore short transverse sections of column-rules have been cast in their final form upon linotype-slugs between the fi ures or characters thereon, so that when the slugs were assembled7 one below another in the form, these sections would join or register and form continuous rules. In practice it was found difficult to secure under the conditions existing in a printing-office the perfect formation and alinement of the rule-sections, and consequently the rules often presented a broken or irregular appearance. In order to overcome this trouble, I'propose to cast the rule-sections on the slugs in an unfinished form and of larger size than required for use. After the typographical errors are corrected and the slugs locked in the form I propose to pass a finishing-tool or machine lengthwise over the rules, thereby reducing them or cutting them down at the printing edge to the nal form demanded. The mechanism employed for this purpose may be of any suitable construction and is foreign to the present invention.

Referring to the drawings, Figure 1 represents a printing-form composed of linotypeslugs having iinished rules thereon in accordance with my invention, one of the slugs being detached. Fig. 2 is a perspective view of one of the slugs, showing two of the rule-sections in the unfinished form in which they are cast and others in the finished form.

Referring to the drawings, A A represent a series of linotype-slugs constituting jointly a printing-form. Each of these slugs bears on one edge a series of letter or figure characters c, arranged in columns, and between these characters transverse rule characters a.

The rule-sections 0f each slug adj oin or register end to end with those on the adjacent slugs, so that the series of sections constitute jointly vertical rules or column-rules adapted to print in the s ame manner as the ordinary brass rules used in type-forms.

In carrying my invention into effect I cast the slugs individually in the ordinary manner each with one or more of the rule-sections thereon. Instead of castin sections in their finished or na form, as heretofore, they are cast, as shown at a2, of large or abnormal size, preferably with a broad or flat upper face. After the slugs are the ruleassembled and locked up with their rule-sections in line I pass over the rules from end to .end a suitable tool-such, for example, as

that commonly used in forming the edge of brass rules-and thereby remove the surplus metal, cutting the rule down to the sectional form and size required for use, as shown, for example, at a.

The printing face or edge may be iinished for single or double, blunt or half-blunt, rules, or, in short, of any size and form required.

The essence of the invention lies in forming the rule-sections of excessive size and thereafter trimming them to the required size and form. While I prefer to assemble the slugs and correct the rules in the form, it is manifest that the correction may be made by proper tools on the individual slugs before they are assembled.

Having described my invention, what I claim is l. The method of producing column-rules in linotype-forms, consisting in forming the rule-sections on the individual linotypes, assembling the linotypes in the form, and thereafter modifyin and correcting the rule.

2. The met od of producing linotypeforms with vertical rules therein, consisting in forming the individual linotypes with rulesections thereon, assembling such linotypes in a form to produce continuous rules, and finally operating upon such rules to modify the sections and bring them into exact alinement.

3.v The method of treating linotypes to I produce column-rules, consisting in forming l each linotype with e rule-section of excessive l size, and thereafter reducing such section to the required size. i In testimony whereof l hereunto set my l hand, this 17th day of April, 1905, in the l presence of two attesting Witnesses.
